H3Y-2 24VDC 5A 3S 250VAC Resistor Time Timer Relay 8-pin

Description

What it is

The H3Y-2 resistive timer relay is an electronic device designed to control high-consumption circuits. This type of relay allows for the automation of the activation or deactivation of electrical devices based on timed programs.

Features

• Operating voltage: 24VDC
• Maximum current: 5A
• Contact numbers: 3S (3 contact forms)
• Voltage AC: 250VAC
• Type: resistive
• Relay type: Time Timer
• Pins: 8pin

What it is for

The H3Y-2 relay is ideal for automating electronic circuits, for example to create an automatic lighting system. It is compatible with Arduino and can be used by beginners and intermediates to control electrical devices.

Tutorial: How to use H3Y-2

The H3Y-2 relay is ideal for controlling electrical devices with a 24VDC power supply. Useful for beginners and intermediates, it serves to automate electronic circuits.

What you need

• H3Y-2
• Arduino
• 24VDC power supply cable
• Wrist strap to test the relay

Steps

1. 1. Check the datasheet for the H3Y-2 relay specifications.
2. 2. Connect the relay to an Arduino using the 8pin pins.
3. 3. Insert a jumper wire between pin 1 and GND to test.
4. 4. Load the provided Arduino code.
5. 5. Turn on the 24VDC power supply.
6. 6. Verify that the relay closes when the power supply is turned on.
7. 7. Add a device to control.
8. 8. Check the operation of the device.

Example code

```void setup() {  pinMode(8, OUTPUT);}void loop() {  digitalWrite(8, HIGH);  delay(5000);  digitalWrite(8, LOW);  delay(5000);}```

Mini project

Create an automatic lighting system. Connect an LED to the relay and program the Arduino to turn the LED on/off.

Common mistakes

• Connect the relay to a different power supply than 24VDC.
• Forget to check the relay operation.
• Install an incompatible device with 24VDC.
• Omit the installation of a device to control.

Recommended accessories
